Transport company resent moving base south (6)
I believe the answer is:
convey
'transport' is the definition.
(conveying is a kind of transporting)
'company resent moving base south' is the wordplay.
I cannot really understand how this works, but
'company' could be 'co' (abbreviation) and 'co' is found in the answer.
'base' could be 'e' (I've seen this in other clues) and 'e' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for convey that I've seen before include "Carry from one place to another" , "Transport or transmit" , "Transport; communicate" , "Make known -- pass on" , "Pass on or transport" .)
